clee i am not one to get involved in arguments wfp vs trad or whatever, but saying doing a job trad will be trashed after the first bit of rain is untrue. and your constant ladders are banned is also untrue as is stating your insurance will not pay out etc.
i have a seventeen year old employee that has been window cleaning longer than you. he can clean trad and wfp with van mount, trolley, backpack as well as ladder, trad pole.
i am well up for a laugh and taking the pee but it does get on peoples nerves sometimes.
anyway back to the subject i dont tend to add more for an 8 weekly clean and i would like to add i have just done an inside clean on a wfp job that was done 3 weeks ago and you can certainly see the outsides need doing soon so its not as wonderfull as we all like to think
